SPECIFICATION forming part of Letters Patent No. 736,626, dated August 18, 1903.

Application filed January 13, 1902. Serial No. 891567. (No model.) 7

T aZZ whom it Hwy concern:

Be it known that I, GIOVANNI PORTA, accountant, a subject of the King of Italy, residing at 61 Via Savona, Milan, Italy, have invented certain new and useful Improvements in Coverings for Demijohns or Similar Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the present invention is a system of envelop or packing cover for fragile receptacles, especially carboys, demijohns, large jars, bottles, and glass barrels, such covering protecting them so effectually as if they were surrounded by an iron girth.

The covering in question consists of a metallic network or trellis applied to the receptacle to be protected, with the interposition of a soft elastic layer with or without hoops, so that the result is a light packing not bulky, but neat, and at the same time endowed with great solidity and durability, elastic, and resisting shocks, some strips of it being specially strong, so as to secure protection of the glass from any concussions to which such receptaelse are liable during transport.

The metallic network will be made in a general way with ordinary machine-made wirenetting, such as is found in commerce. The flat netting will be reduced and adapted to the form (nearly oval, conical, hemispherical, the.) of the receptacle by stretching, taking advantage of the property of the netting itself, which allows of its being stretched properly, modifying in various ways the single meshes, so as to increase or diminish in any degree or direction required the superficial development of the netting itself until it is made to adhere perfectly to the shape of the receptacle. This new and special use for the said flat machine-made metallic netting is extremely advantageous and cheap. As is shown on the drawing, the network is applied under a strong tension, so that the soft elastic underlyinglayer is pressed against the glass, whereby it acquires considerable elasticity, and at the same time the difierent parts of the packing, and especially the bottom, stick fast to each other. Besides that, the packing turns out perfectly adherent to the receptacle and takes the exact shape of the latter, so as to give to the whole a very neat and pleasant appearance. 7

The underlying layer of soft and elastic matter will in general be formed of twisted or tressed straw; but the employment of any other convenient material adapted thereto is not to be excluded. Its thickness will be regulated according to the requirements in any special case.

The hoops, if any, will usually be of metal, mostly of iron; but they may also be of any other material.

The hereto-annexed drawing is an elevation, partly in section, of a demijohn provided with my improved envelop, which I call an iron girth. Three hoops are shown in this special case-namely, a central one A, to which are attached the handles M for transport, an upper one B, on which is fixed the cap N for stopping and protecting the neck of the demijohn, and a lower one C, which holds in its place the bottom 0, of wood, sheet-iron, or other material. On the left side of the layer, which is a section, the soft stratum P is to be seen, while in the elevation on the right the network is visible.

This system of covering may also be applied partially, and so, for instance, for carboys, demijohns, jars, bottles, &o., intended for 10- cal use, for the transport of acids, 850., the covering mayin this case be restricted to the lower part only as far as the middle hoop A or otherwise, as the case may require.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-- 1. In combination with a demijohn or the like, a layer of straw encircling the same, a wire-netting encircling, the straw and a series of hoops placed at intervals around the wirenetting for holding said netting and straw to the demijohn.

2. In combination with a demijohn or the 5 like, a layer of straw encircling the same, a

wire-netting encircling the straw, hoops encircling the demijohn, outside the wire-netting, at the top and bottom thereof, and a hoop encircling the middle portion of said demijohn.

In witness whereof I have hereunto set my hand in presence of two witnesses.
